The toxin produced by Shigella dysenteriae that acts as an enterotoxin, causing necrosis of the cells of the colon, is Shiga toxin.

The main mode of transmission for Shigella spp. is through the fecal-oral route, often via contaminated food and water.

Clinical signs of Shigella dysenteriae infection include abdominal cramps, diarrhea, fever, and tenesmus (a feeling of incomplete bowel evacuation).

The recommended treatment for Shigella dysenteriae infection is antibiotic therapy, specifically with fluoroquinolones or cephalosporins, to shorten the duration of illness and reduce the risk of complications.

The most effective prophylaxis for Shigella dysenteriae infection is proper hand hygiene, particularly washing hands with soap and water, to prevent the spread of the bacteria.
